## Job description

## About Radiant

Radiant is an El Segundo, CA-based company building the world's only mass-produced, transportable nuclear microreactors. The U.S. grid is under growing strain, with power demand accelerating, driving higher utility costs, rising carbon emissions, and interconnection backlogs. Radiant has a solution, transportable, on-site power. Our first reactor, Kaleidos, is 1 megawatt: small enough to be factory-built, transported by land, sea, or air, and deployed wherever power is needed. 1 MW can power 1000 homes for five years. Ship it back and we refuel for a 20 year operating life. We made energy a product that can be used for critical infrastructure like military bases, data centers, hospitals, and remote sites, as well as the commercial main street businesses that keep America running. Founded in 2020, Radiant is under contract to deliver power to the U.S. Army, Navy and Air Force and has signed pre-order agreements with Equinix, with deployments beginning in 2028.

## About Radiant Industries

## Company Overview
- **One-liner**: Radiant Industries is building the world’s first mass‑produced, portable nuclear microreactor (Kaleidos) to replace diesel generators with zero‑emission, resilient power for remote sites, hospitals, data centers, and military installations.
- **Entity Type**: Private (Series D – $300M raised in December 2025, led by Lockheed Martin Ventures)
- **Headquarters**: El Segundo, California, USA
- **Founded**: 2020 (some sources list 2019)
- **Founders**: Not publicly disclosed

## Core Business

## Products & Services
- **[Kaleidos Microreactor](https://www.radiantnuclear.com/)**: A 1 MW electric / 1.9 MW thermal portable nuclear reactor packaged in a shipping container. It uses helium gas cooling and TRISO fuel (meltdown‑proof ceramic uranium particles). Delivered by truck or aircraft, installed without site excavation, and can reach full power the next day. After 5+ years the entire container is returned to the factory for refueling; up to four fuel cycles yield a 20‑year product lifetime. Customers purchase via Power Purchase Agreements (PPAs) or direct unit sales.

## Market Standing

## Competitive Advantages
- **Portability & speed**: Delivered in a standard shipping container, installed in one day, no on‑site water or excavation needed.
